After reaching the checkpoint, a Warp Pipe will allow access to the second part of the level. This part is an underground cave with many Spinies and Fire Bros.

Star Coins

Star Coin #1: Use the springboard at the beginning of the level, and once you see the Star Coin in plain sight, bounce off the springboard. Watch out for the Angry Sun.

Star Coin #2: The Yellow Switch is recommended for this Star Coin. Once the Info Block is reached, go to an alcove to the left of the first falling quicksand abyss, then go into the green Warp Pipe. The Star Coin is visible upon entering. Though you have to be careful, since Venus Fire Traps are everywhere.

Star Coin #3: Hit the right Brick Block that the second Fire Bro is guarding to reveal a P-Switch. Hit it, and follow the quicksand abyss of blue coins resembling an arrow. Upon entering, do a running jump to get the Star Coin.
